This is a comprehensive Periodic Table Lab Activity Simulation for students. There are 3 documents:
1) Lab Introduction Document with Questions and setting the context to examine unknown elements from the Planet Pumpernickel
2) 9 page flash cards of unknown alien elements that have element properties of atomic radius, electronegativity, ionization energy, conductivity, electron configuration, etc.
3) Answer Key for the most consistent element arrangement
I found this to be most successful when I had students in groups of 3 or 4. I gave each group an envelope with the cut up element cards (I placed them in an envelope) and asked them to arrange it in the most logical pattern. I was not looking for one right answer technically so feel free to let them arrange the elements in any order so long as they can justify it!
Also, feel free to let your first period class help you cut up the cards so they can help in the process of the activity/lab.
